The closed-back MrSpeakers AEON Flow headphones are one of the best sealed-back models I've ever tried. This open-back version is just as special. It features the same look, build-quality, and cutting-edge planar magnetic drivers. The big difference is the stainless steel grill that allows more air to move in and out.

Open-air version of an underground hit

The closed-back MrSpeakers AEON Flow headphones are one of the best sealed-back models I've ever tried. This open-back version is just as special. It features the same look, build-quality, and cutting-edge planar magnetic drivers. The big difference is the stainless steel grill that allows more air to move in and out.

My first impression

I've just started listening to this open-back version, but like what I've heard so far. While they don't offer the isolation of the closed-back model, they do offer a slightly more spacious sound. The bass is also surprisingly strong and detailed for an open-back headphone.

Who is Mr. Speakers?

I met company founder Dan Clark — THE Mr. Speakers — at CanJam NYC 2018. Dan is an interesting guy. His passion for headphone-making is only rivaled by his love of music. He's as quick to drop a story about his favorite band as he is to break down his patented TrueFlow™ technology (more on that later).

He told me that while he uses the latest technology and measurement instruments available, he also takes a more "gut-feeling" approach to his craft. "I don't consider myself done with a set of headphones," he said, "until I hear a familiar song through them, and it moves me in a new way."

The origin story

Dan is a longtime audio engineer who made a name for himself by modifying other manufacturers' headphones. Hardcore headphone enthusiasts appreciated his semi-"outlaw" approach, and really loved Dan's sound improvements.

Capitalizing on the buzz, Dan started his own brand, MrSpeakers. He gathered some talented people, and they began building headphones from scratch in their San Diego shop. Those early MrSpeakers planar magnetic headphones earned rave reviews, and their reputation has only grown.

The company's latest top-of-the-line ETHER Flow and ETHER C Flow headphones are on many "Best of" lists. Those two models informed the design of these AEON Flow headphones. They use the same specially designed planar magnetic drivers. Modern manufacturing techniques like 3D printing helps them deliver premium high-end performance at surprisingly low prices.

A new take on planar magnetic headphones

Planar magnetic designs can get complex, but the basic physics behind them are pretty simple. You have a super-sized diaphragm moving lots of air, resulting in spacious sound with better dynamics. The diaphragm is covered with a flexible circuit and trapped in a magnetic field. It moves when the circuit receives an audio signal.

MrSpeakers added a new wrinkle to this traditional design. Or perhaps more accurately, a few creases. Rather than using a completely flat diaphragm that can bounce back and forth rigidly, their V-Planar™ drivers use a more fluid-moving pleated diaphragm. This accordion-like pattern helps it start and stop quickly, pushing more air. You can really hear the extra presence on tracks with complex bass.

Lightweight and efficient

To move a diaphragm this large, most drivers have a magnet array on both sides. That's why planar magnetic headphones sound great, but are usually heavy and bulky. The V-Planar drivers use a single-sided magnet design, so they are efficient enough to plug directly into a phone. (Of course, they'll really shine when you drive them with a more robust headphone amp.) Plus they feel lighter than any other over-ear planar headphones I've ever worn.

Smoother airflow around the magnets

MrSpeakers also includes their TrueFlow™ waveguides on either side of the magnet array. These special baffles help reduce turbulence in the airflow. This lowers distortion and makes for effortless, natural sound.

Airflow around planar magnet arrays can get messy...

... so MrSpeakers added the TrueFlow waveguides to reduce turbulence.

Incredible build and comfort

The six-foot, soft-fabric-covered cable connects to each earcup using a heavy-duty locking system. A simple adjustment of the leather inner headband will correctly position the teardrop-shaped earcups. The nickel-titanium outer headband is strong, extra-flexible, and it helps everything slide into place.

MrSpeakers AEON Flow Reviews

MrSpeakers AEON Flow

Have not broken in yet, however they are sounding better each time I use them. That's the only reason I didn't give 5 stars. Will have to wait a little
longer, after break in to re- review. Fit and finish are very good. So far very happy.

Features

Overview: The MrSpeakers ÆON Flow (Open Version) is an
over-ear planar magnetic headphone. Its open design lets in ambient sounds, so
it's more like listening to a pair of speakers in a room. These audiophile-grade headphones feature
V-Planar and Trueflow technologies, and are precision
crafted to deliver superb performance. Their low impedance (13Ω) and higher
efficiency (95dB/mW) makes them significantly easier to drive with a smartphone
or tablet. For best performance, you should use a
high-quality headphone amplifier with the headphones.

Note: The ÆON Flow
Closed Version is also available for those who wish to shut out external
noise while they listen to music.

Planar Magnetic Drivers: The ÆON Flow uses planar magnetic
drivers which deliver much better performance over standard dynamic drivers. The
result is more balanced sound with a wide open soundstage.

Tuning: The ÆON Flow headphones come with tuning materials
to let you customize the sound of your headphones. Three pairs of pads are
provided for inserting in the ear wells of the headphones. It is recommended
that, instead of going back and forth, you should listen to each option over an
extended time to fully understand the differences. The tuning pads are as
follows:

Black: This black foam ear pad is the most porous and
provides the least amount of damping. The foam pads increase the upper bass
output and tone down the highs a bit.

White 1-notch: The white felt ear pads with a single
identifying notch are pre-installed in the headphones. They provide a medium
amount of damping.

White 2-notch: The white felt ear pads with dual
notches have the most amount of damping of the three sets of pads.

Construction: The ÆON Flow headphones features genuine
carbon fiber ear cups to house the 62mm x 34mm (2.44" x 1.34") planar
magnetic drivers. Two thin NiTinol memory metal bands hold the ear cups
together, and provides the right amount of pressure on the head. NiTinol is a
Nickel Titanium metal alloy that returns to its original shape, even after being
severely bent. The soft dyed leather headband lies softly on the top of the head
while the leather-covered foam ear pads provide a good seal to isolate a lot of
the outside noise. The outer portion of the earcups features a window showing
the carbon fiber weave pattern, framed in midnight blue/black metallic paint.

DUMMER Cable: The MrSpeakers ÆON Flow comes with the 6.5'
detachable DUMMER (Distinctly Un-Magical) cable, which features a 3.5mm plug
with a screw-on 1/4" adapter. The fabric-covered Y-type cable
features 4-pin connectors on the headphone end.

great reviews and Tyll in his retirement is taking these on his adventure across the country, so if the respected headphone journalist,/chief headphone advocate & pioneer is taking these with him over all others on his wall of fame, then that's good enough for me.
